Sines LNG Terminal

Sines LNG Terminal, operated by REN Atlântico under a 40-year concession, is Portugal's only LNG receiving facility and one of the Iberian Peninsula's most important gas import points. Located at the deep-water Port of Sines on Portugal's Atlantic coast, the terminal has been operational since 2003 and has three LNG storage tanks with a combined capacity of 390,000 m³, handling vessels from 40,000 to 216,000 m³. In normal operations it processes over 60% of Portugal's natural gas consumption. The terminal recorded its 500th LNG cargo in a milestone delivery, and set import records in 2022 as European demand surged following Russia's invasion of Ukraine.

REN Atlântico is a subsidiary of REN (Redes Energéticas Nacionais), the Portuguese state-linked energy network company. The terminal's concession structure means Portugal's government has a direct policy lever over its operation. Sines' Atlantic position and deepwater berths make it capable of receiving large conventional LNG carriers and, when economics allow, reloading for Onward distribution to smaller European terminals.

Like Fos Cavaou, EemsEnergy Terminal, and Panigaglia, Sines recorded low utilisation in Q1 2026 amid elevated European storage and reduced spot LNG demand. Portugal's heavy dependence on the single terminal creates vulnerability: any extended outage forces reliance on Spanish interconnector gas. REN Atlântico has explored capacity expansion and reload services to broaden the terminal's commercial use cases beyond domestic supply.
